Apologies if this has been done to death- I've done a search but not come up with a definite answer to my queries.
Scenario- concrete block garage 6400 x 9100 internal dims with buttresses. Floor spec- min 100mm hardcore (it'll be 150 in places, subsoil wasn't particularly level) whacked down in 25mm layers, 25mm blinding sand, DPM, 100mm concrete- using readymix or whatever, hand-batching 6 cubic metres doesn't appeal. Loading- heaviest thing in there will be a 7.5 ton van.
Detail- to be in with a shout of getting a level floor I'm contemplating doing it in 2 batches- shutter off (and batten walls) for 6 squares about 3000 x 3000. Pour rear left, middle right, front left squares (with excessive DPM poking up above the shuttering), tamp finish. Leave for 2 or 3 days. Remove shuttering boards, lay and tape DPM for other squares, pour rear right, middle left, front right, tamp finish. Wait for about 2 weeks, slather with garage floor paint to give nice smooth finish
Questions;
Does this sound reasonable?
Does this sound doable for 2 of us (I can get the concrete wagon to the garage door so no massive barrow runs required)
Do I need to put any sort of divider between the squares?
Does the DPM have to bond with the DPC in the walls (please say no, 150mm of black plastic is going to look sooooo shoddy)
